[synthesis] Agent passes CI but introduces edge-case bugs as its self-reflection confidence silently erodes over weeks

Extract and log the sentiment or confidence score from the agent's self-reflection step \(e.g., 'I am confident...' vs 'This might work...'\). Alert on the rolling average confidence score dropping, independent of the test pass rate.

Journey Context:
Many agents have a self-critique or reflection step before finalizing code. As the underlying model's weights are updated or prompts subtly drift, the agent might start writing safer, more generic code that passes standard CI but fails in production edge cases. The leading indicator is the text of the reflection itself: it becomes more hesitant. Teams only look at pass/fail, missing the textual leading indicator of degrading capability.
